【考點(diǎn)直擊】
按照句子的用途，英語(yǔ)句子可分為陳述句、疑問(wèn)句、祈使句和感嘆句。按照句子的結構，英語(yǔ)句子可分為簡(jiǎn)單句、并列句和復合句。中考對句子的考查主要集中在以下幾個(gè)方面：
1. 陳述句的構成形式及基本用法；
2. 祈使句的構成形式及基本用法；
3. 一般疑問(wèn)句、特殊疑問(wèn)句、選擇疑問(wèn)句、反意疑問(wèn)句的構成形式及基本用法；
4. 由what, how引導的感嘆句的構成形式、用法及區別
對于各種從句的用法我們在后面分別論述。
【名師點(diǎn)睛】
一. 陳述句的構成形式及基本用法
1. 陳述句：
陳述句是用來(lái)陳述一個(gè)事實(shí)或表達說(shuō)話(huà)人看法（包括肯定和否定）的句子。通常用降調，句末用句號“.”。
Tom has a new car.
The flower isn’t beautiful.
2. 陳述句否定式的構成
(1) 如果肯定陳述句的謂語(yǔ)部分含有助動(dòng)詞、情態(tài)動(dòng)詞或連系動(dòng)詞be，則只需在這些動(dòng)詞后加not即可構成否定式。
He is playing the guitar.（肯定）
He is not playing the guitar.（否定）
We can get there before dark.（肯定）
We can’t get thee before dark.（否定）
(2) 如果陳述句的謂語(yǔ)動(dòng)詞是實(shí)義動(dòng)詞，而其中又沒(méi)有情態(tài)動(dòng)詞或助動(dòng)詞時(shí)，則需根據人稱(chēng)和時(shí)態(tài)在該實(shí)義動(dòng)詞前加don’t, doesn’t或didn’t。同時(shí)把該實(shí)義動(dòng)詞變?yōu)樵巍?/p>
He plays the violin well.（肯定）
He doesn’t play the violin well.（否定）
She won the game.（肯定）
She didn’t win the game.（否定）
(3) 如果句子是there be結構或謂語(yǔ)動(dòng)詞是have（有），除了be和have之后加not之外，句中如果有some要變?yōu)閍ny。例如：
There is some water in the cup. →There is not any water in the cup.
He has some books. →He has not any books.
(4) 除not以外，否定詞no, never, nothing, nobody, few等也可構成否定句。例如：
There is something wrong with his bike. →There is nothing wrong with his bike.
I have seen the film. →I have never seen the film.
二. 祈使句的構成形式及基本用法
祈使句是用來(lái)表示命令、請求、建議、號召等的句子，謂語(yǔ)動(dòng)詞用原形，句末用感嘆號“！”或句號“.”。朗讀時(shí)一般用降調。
1. 肯定的祈使句：
?。?）祈使句主語(yǔ)是you時(shí)，you常省略，但如果要特別強調對方或表達某種強烈的情緒時(shí)可以有主語(yǔ)或稱(chēng)呼語(yǔ)。
Be quiet.
You be quiet!
?。?）“Do+祈使句”表示一種強烈的感情或請求，do起強調作用。
Do come back at once!
Do be careful.
?。?）please用在祈使句中可以表示一種客氣的語(yǔ)氣，但please用在句末時(shí)，必須用逗號與其余部分分開(kāi)。
Open the window, please.
?。?）Let引導祈使句時(shí)，后面需跟上人稱(chēng)代詞或稱(chēng)呼語(yǔ)，人稱(chēng)代詞一般只用第一、第三人稱(chēng)。
Let Jack wait a minute.
Let’s go to school.
?。?）在祈使句中，Let’s和 Let us是有區別的。Let’s包括說(shuō)話(huà)者，而Let us不包括聽(tīng)話(huà)者在內。這點(diǎn)從反意疑問(wèn)句時(shí)可明顯看出。
Let’s go skating, shall we?（表示內部的建議）
Let us try again, will you?（表示向別人發(fā)出請求）
2. 否定祈使句通常以Don’t或Never開(kāi)頭。其結構通常是：“Don’t(Never)+動(dòng)詞原形+其他成分” 例如：
Don’t do that again!
Never leave today’s work for tomorrow!
Don’t be late next time!
三. 一般疑問(wèn)句、特殊疑問(wèn)句、選擇疑問(wèn)句、反意疑問(wèn)句的構成形式及基本用法
1. 一般疑問(wèn)句：
（1）一般疑問(wèn)句的肯定形式
一般疑問(wèn)句一般是指以助動(dòng)詞、情態(tài)動(dòng)詞、be動(dòng)詞或have（有）開(kāi)始，通常要求以yes，或no來(lái)回答的疑問(wèn)句，一般疑問(wèn)句讀時(shí)通常用升調。
Do you know Mr. Smith?
Can you swim?
（2）一般疑問(wèn)句的否定結構
① 在一般疑問(wèn)句的否定結構中，把副詞not放在一般疑問(wèn)句的主語(yǔ)之后。但如果用not的簡(jiǎn)略形式-n’t，則須將-n’t與一般疑問(wèn)句句首的be, have，助動(dòng)詞或情態(tài)動(dòng)詞寫(xiě)在一起。在實(shí)際運用中，一般都采用簡(jiǎn)略式。
Are you not a football fan?
Aren’t you a football fan?
Will she not like it?
Won’t she like it?
② 與漢語(yǔ)不同的是，英語(yǔ)一般疑問(wèn)句否定結構的答語(yǔ)是否定還是肯定，全由答語(yǔ)的否定或肯定來(lái)決定。若答語(yǔ)是肯定的，則用yes加肯定結構；若答語(yǔ)是否定的，則用no加否定結構。
Aren’t you a football fan? 你不是足球迷嗎？
Yes, I am.
No, I am not.
Won’t she like it?
Yes, she will.
No, she won’t.
2. 特殊疑問(wèn)句
特殊疑問(wèn)句由“疑問(wèn)代詞或疑問(wèn)副詞+一般疑問(wèn)句”構成，句子一般用倒裝語(yǔ)序，但如果主語(yǔ)是疑問(wèn)代詞或由疑問(wèn)代詞修飾時(shí)，用陳述句的語(yǔ)序。特殊疑問(wèn)句不能用yes或no回答，讀時(shí)用降調。例如：
Who is on duty today?
How long have you been in Beijing?
What time do you get up every morning?
What must I do now?

3. 選擇疑問(wèn)句：
選擇疑問(wèn)句是說(shuō)話(huà)者提出兩種或兩種以上的不同情況，讓對方選擇回答的疑問(wèn)句。其結構是“疑問(wèn)句+選擇部分”。選擇部分由or連接，or前面的部分讀升調，or后面的部分讀降調。
選擇疑問(wèn)句不能用yes或no回答，而必須具體的選擇答復。
Is your bag yellow or black? It’s black.。
Would you like some tea or coffee? Either will do.。
Which do you like better, singing or dancing? I like dancing better.
4. 反意疑問(wèn)句：
反意疑問(wèn)句是指在陳述句之后附加一個(gè)意思與之相反的簡(jiǎn)短問(wèn)句，問(wèn)對方是否贊同的疑問(wèn)句。附加問(wèn)句的否定式必須縮寫(xiě)。
?。?）肯定的陳述句后跟否定的附加問(wèn)句，否定的陳述句后跟肯定的附加問(wèn)句。
I am your teacher, aren’t I?
He didn’t study hard, did he?
?。?）如果陳述句中含有否定副詞never（從不，決不），hardly（幾乎不）或其他表示否定代詞或形容詞，如nothing, none no one, nobody, neither, few, little等，則附加問(wèn)句只能用肯定式。如：
They hardly write to each other, do they?
He has found nothing, has he?
Few people knew the secret, did they?
?。?）當反意疑問(wèn)句是“否定陳述句+肯定附加問(wèn)句”時(shí)，英語(yǔ)與漢語(yǔ)的回答習慣存在差異。英語(yǔ)回答時(shí)只看實(shí)際情況，若答語(yǔ)的具體內容是肯定的就用“Yes+肯定結構”，答語(yǔ)的具體內容是否定的就用“No+否定結構”，而譯成漢語(yǔ)時(shí)，則必須把yes譯“不是”，把no譯成“是的”。
---You won’t be away for long, will you? 你不會(huì )離開(kāi)太久，是嗎？
---Yes, I will.不，我會(huì )離開(kāi)很久。
---No, I won’t.是的，我不會(huì )離開(kāi)很久。
---I don’t think she’ll come by bike, will she? 我認為她不會(huì )騎自行車(chē)，會(huì )嗎？
---Yes, she will.不，她會(huì )騎自行車(chē)來(lái)。
---No, she won’t.是的，她不會(huì )騎自行車(chē)來(lái)。
四. 由what, how引導的感嘆句的構成形式、用法及區別
感嘆句是表示喜、怒、哀、樂(lè )以及驚異等感情的句子。句末用感嘆號“！”，讀時(shí)用降調，感嘆句往往由what或how引導，what修飾名詞，how修飾形容詞，副詞或動(dòng)詞。
1. what引導的感嘆句：
?。?）what + a/an +形容詞+單數可數名詞+陳述句（主語(yǔ)+謂語(yǔ)）
What a beautiful city it is!
What an interesting story she told!
?。?）what+形容詞+復數可數名詞/不可數名詞+陳述句（主語(yǔ)+謂語(yǔ)）
What expensive watches they are!
What terrible weather it is!
2．How引導的感嘆句：
?。?）How+形容詞/副詞+陳述句（主語(yǔ)+謂語(yǔ)）
How cold it is!
How hard he works!
?。?）How+陳述句（主語(yǔ)+謂語(yǔ)）
How he loves his son!
How I miss you!
?。?）How+形容詞+a/an+單數可數名詞+陳述句（主語(yǔ)+謂語(yǔ)）
How tall a tree it is!
?。?）上述兩種感嘆句可以互相轉換。例如：
What a clever boy he is!→How clever the boy is!
What a cold day it is!→How cold it is!
【實(shí)例解析】
1. (2004年上海徐匯區中考試題)
_________ useful computer it is!
A. What B. What a C. What an D. How
答案：B。該題考查的是感嘆句的結構。這個(gè)感嘆句的中心詞是一單數可數名詞computer, 所以要用what來(lái)修飾，又因為useful第一個(gè)發(fā)音是輔音，what之后的不定冠詞用a,而不用an。
2. (2004年嘉興市中考試題)
---________ is it from Jiaxing to Hangzhou?
---I’m not sure, but it takes about ninety minutes to get there by bus.
A. How many B. How often C. How much D. How far
答案：D。該題考查的是特殊疑問(wèn)句疑問(wèn)詞的選擇。問(wèn)話(huà)者是在問(wèn)距離，所以應用how far來(lái)提問(wèn)。
3. (2004年河北省中考試題)
---_______ will it take us to get there by bus?
---About two hours.
A. How soon B. How often C. How long D. How quick
答案：C。該題考查的是特殊疑問(wèn)句疑問(wèn)詞的選擇。問(wèn)話(huà)者是在問(wèn)時(shí)間，所以應用how long來(lái)提問(wèn)。
4. (2004年長(cháng)沙市中考試題)
---Help! There is a snake near the house.
---________ afraid. It will go away later.
A. Don’t B. Not C. Don’t be D. Be
答案：C。該題考查的是祈使句的結構。祈使句的否定結構是：“Don’t(Never)+動(dòng)詞原形+其他成分” 符合這一要求的只有C。
